and a ring; and, secondly, in the combination,

with the draw-center of a grate, of upwardlyprojected teeth arranged at the frontend, as will be hereinafter more fully set forth.

Accompanying this specitication,and forming a part of it, are three plates of drawings, in all of which the same letter-reference as to 4 the designation ot' parts is used.

a Figure l illustrates a central vertical sectionv ot' a parlor heating-stove, taken from front to rear, through the bottom of the magazine section, combustion-chamber section, tire-pot,

grate, and at right angles to the grooves formed intheash-chute wall to receive theash-drawe'r. It also shows the relative position of the grate and the bottom ofthe fire-pot, the projections formed in the latter being indicated by a dotted line. This section also shows theposition of the engaging Hanges formed on the bottom ofthe magazine-section andthe top ofthe combustion-chamber and the manner of securing them by nuts and bolts. It also shows a centra] vertical section of the contained surbase and the ventlating-apertures formed in the exterior curtaned walls of the inclosure and in the diaphragm-plate, with arrows designat-` ing the direction of the Ventilating-currents.

Fig. 2 shows in perspective the grate re support the grate, and which projections divide up the spaces formed between the top of the lgrat-e and the bottom of the tire-pot when the grate is in position. Fig. 3 shows a view in 'perspective of the' usual draw-center, which is provided with a central opening to receive a fitted brick or soapstone. It also illustrates, as constructed at its front, a series of-upwardly-curved teeth, which, when the gratie is vibrated, serve the saine purpose as the projections upon the top and outer edge of grate, to clean out the space between the grate and lirepot.

The several parts are designated by letterreference, and their operation described, as follows:

At M Mis shown the bottom ot' the magazine-section, which is cast with the inwardlyprojecting flange F' F', and upon the top of the combustion-ch amber C, at F F", is shown another flange, which faces onto thel one cast on the bottom of the magazine-section.

At B B are shown vertical bolts, which pass through these engaging lianges, and are secured by nuts.

P P designate the tire pot, edge; GG, the grate; R, its exterior ring; O O, projections formed on the top of the grate and subtending the outer edge of the latter, so v grate is rotated within the ring by meansof the handle H, the projections, in their vibration clean oli' the ring and the space between the bottom of the tire-pot and top of the grate, andthese projections divide oft' this clinkervcleaning space, so that it is not continuous.

At C Gis designatedan ash-chute, a nd there is shown as `constructed in it the groove D, formed to receive the ash-drawer A, which has a projecting rim at the top (designated at e) At B there is shown the ordinary and usual base, and at B a curtained sub-b se having the diaphragm-plate E. In gress air-apertures are designated in the curtained exterior at a" and in the diaphragm-plate at a", and egressopenings are shown in the curtained exterior of the surbase at the-topas designated at a. Direction arrows are arranged to show the movement of the Ventilating-currents.

The letters p p denote the curtained exterior of 'the sub-base.

AtjS S" S are shown toothedV projections upon the front of the grate draw-center G".

l am well aware that it is not new to form a clinker-cleaning aperture between the top ot' the grate and the bottom ofthe tire-pot where either the olinker-cleaning aperture was contin-4 and S S its lower nous or wherea grate and ring; having agreater area than the bottom of the lire-pot were combin ed with the latter to produce a olinker-oleaning aperture. My invention in this respect is limited to the construction I employ to avoid a. continuous opening by dividing up the clinkercleaning space by means of projections, which clean the ring' and spaces when the grate is r0- tated.

*Having thus described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a parlor heating-stove, the combinationof the tire-pot P, the grate G, the ring-R,

surrounding the latter, and the projections O O, constructed on the top and at the outer edge ofthe grate, so as to divide up the olinkereleaningspace between the top of the grate and the bottom of the fire-pot, substantially'as set forth.

2. In combination with the draw-center of a grate, the upwardly-projected teeth S S" S, arranged at the front, as and for the purposes described and set forth.

Signed at Troy, New York, this 4th day of January, 1881.
